Answer:46.05 mm
Explanation:
Given

speed 
allowable shear stress 
Power is given by



From Torsion Formula

where J=Polar section modulus
T=Torque
=shear stress
For square cross section

where a=side of square

Substituting the values in equation 1



Answer:
there are 1,000m in a km, so 200km is 200,000m
200,000m/10m/s = 20,000s

Answer:
0.061 J
Explanation:
The kinetic energy of an object is given by

where
m is the mass of the object
v is its speed
For the toy truck in the problem, we have
m = 0.1 kg is its mass
v = 1.1 m/s is its speed
Putting the numbers into the equation, we find

Answer:
AAT-CAG-GT
AAT-CGA-GT
Explanation:
Because they are both missing one letter
Answer:
30 C
Explanation:
Given:
Current flowing in the circuit (I) = 50 A
Start-up time (t) = 0.60 s
Now, we know that, charge drawn in through a cross sectional area of the circuit is given as:

Where, 'q' is the amount of charge drawn, 'I' is the current and 't' is the start-up time.
Now, plug in 50 A for 'I', 0.60 s for 't' and solve for 'q'. This gives,

Therefore, the amount of charge drawn in the circuit at the start-up of the compressor of an air conditioner is 30 C.
